NY09016 - Environmental and Technical Extension

Five sub projects were investigated as part of this project and this report details the outcomes associated with these sub projects. The NGI has been successful in implementing the key objectives of the project with the following outcomes having been achieved:

  • Development of four key pest contingency plans for high risk biosecurity pests of the NGI to ensure the industry can appropriately manage these pests should there be an incursion. Contingency plans were developed for:

o Whitefly transmitted viruses
o Poinsettia thrips (Echinothrips americanus)
o Gypsy moth (Asian and European strains) Lymantria dispar dispar
o Serpentine leaf miner (Liriomyza huidobrensis)

  • Completion of three university student projects that addressed key environmental issues whilst educating tomorrow’s future industry leaders. Projects undertaken and successfully completed during this project included:

o Using STRATUM to estimate the benefits of street trees in Melbourne - University of Melbourne, Victoria.
o Bottom ash as a green roof substrate - University of Melbourne, Victoria.
o Does biochar have a role in growing media? Sydney University, Sydney.

  • A scientific report that investigated whether irradiation on live plants could be used as an alternative quarantine treatment.
  • Development of an online calculator to facilitate grower assessment of nursery energy requirements across all operations, potential alternative energy sources and cost benefit assessment of options. Accompanying this calculator were resources to inform the NGI on opportunities and costs associated with energy cogeneration including case studies and fact sheets relating to solar power and wind turbines.
  • A literature review and scientific report that investigated the degree of herbicide residues in dam water following herbicide applications at production nurseries.
